Tuberculosis is the leading cause of morbidity and mortality among children living with the human immunodeficiency virus (HIV), mainly in sub-Saharan Africa, including Ethiopia. Tuberculosis remains a significant health concern for HIV-positive children in Ethiopia. There is a paucity of data on the incidence and predictors of tuberculosis among children living with HIV on antiretroviral therapy in the Wolaita zone. Hence, this study aimed to assess the incidence and predictors of tuberculosis among children living with HIV on antiretroviral therapy in the Wolaita zone between January 2010 to December 2020.. A retrospective cohort study was conducted among 389 children receiving antiretroviral therapy in Wolaita zone health facilities between January 2010 to December 2020. The checklist was adapted from the standardized antiretroviral treatment (ART) follow-up form currently used by the institutions' ART clinics. The Kaplan-Meier survival function and Log-rank were used to estimate the survival for each categorical variable to compare the survival between different exposure groups. Both bivariable and multivariable parametric survival Gompertz models were fitted to identify predictors of tuberculosis among HIV-positive children. The association was summarized using an adjusted hazard ratio (AHR), and statistical significance was declared at 95% CI and p-value < 0.05. The goodness of the model fit was assessed using a Cox-Snell residual plot.. The incidence rate of tuberculosis among children living with HIV was 3.5 (95% CI 2.7-4.5) per 100 child years. World Health Organization clinical stage III or IV (AHR = 2.31, 95% CI [1.26, 4.22]), hemoglobin level <10 g/dL (AHR = 2.87, 95% CI [1.51, 5.45]), fair or poor ART adherence (AHR = 4.4, 95% CI[2.18, 9.05]), underweight (AHR = 2.55, 95% CI [1.45, 4.51]), age >10 years (AHR = 3.62; 95% CI [1.29, 10.0]), and cotrimoxazole preventive therapy (AHR = 0.23; 95% CI [0.08, 0.60]) were among the independent predictors of TB occurrence.. The incidence of tuberculosis among children on ART was high. HIV-positive children presenting with advanced disease staging (III and IV), anemia, "fair" and "poor" ART adherence, underweight, age above ten years, and not receiving cotrimoxazole preventive therapy were at higher risk of TB. Therefore, counseling on ART adherence, early diagnosis, and prompt treatment of anemia and malnutrition are recommended to avert tuberculosis.

Epilepsy is one of the most common neurologic disorders worldwide with no distinguishable cause in 60% of patients. One-third of world's population is infected with Toxoplasma gondii (T. gondii). This intracellular parasite has high tendency to excitable cells including neurons. We assessed seizure susceptibility and involvement of dopaminergic system in male mice with acute and chronic T. gondii infection. Mice were infected by intraperitoneal injection of T. gondii cysts. Acute and chronic stages of infection were determined by quantification of SAG1/BAG1 transcripts and level of repetitive REP-529 sequence in the brain of mice by real-time PCR. Threshold of clonic seizures was measured by tail vein infusion of pentylenetetrazole. The infected mice were pretreated with D1 and D2 dopamine receptor antagonists, and seizure threshold was measured. Moreover, seizure threshold was determined after treatment of toxoplasmosis by sulfamethoxazole and trimethoprim. SAG1 level reached the maximum at week 2 after infection and then declined. The maximum level of BAG1 was observed at the week 3 and preserved till the week 8. REP-529 was detected at first week after infection, reached maximum at the week 3 and kept at this level till the eighth week. Threshold of seizures significantly decreased in both acute and chronic phases of infection. D1 and D2 receptors antagonists inhibited proconvulsant effect of toxoplasmosis. Chemotherapy inhibited parasite growth and multiplication, and returned seizure susceptibility to the level of non-infected mice. Dopaminergic neurotransmission participates in proconvulsant effect of T. gondii. The effect of parasite is eliminated by antibiotic therapy. © 2017 Wiley Periodicals, Inc.

A 4-year-old boy with acute lymphoblastic leukemia who was receiving 6-mercaptopurine during the maintenance chemotherapy experienced prolonged generalized tonic nocturnal seizures because of severe hypoglycemia after his evening dose by a 12-hour period of fasting. Investigations ruled out all causes of these seizures other than the 6-mercaptopurine-induced severe hypoglycemia.

Co-trimoxazole (trimethoprim-sulfamethoxazole) is a commonly prescribed antimicrobial agent. Although it is well tolerated in most patients, serious adverse events related to its use have been described. Hypoglycaemia is a rare but potentially life-threatening complication of therapy. We describe a case of refractory hypoglycaemia complicated by seizure associated with co-trimoxazole for the treatment of Pneumocystis carinii pneumonia in a patient with AIDS. We also review 13 previously reported cases of co-trimoxazole-induced hypoglycaemia. Among this patient population, renal insufficiency was the most prevalent predisposing risk factor (93%). The mean daily dose of co-trimoxazole was 4.5 double strength (160 mg trimethoprim/800 mg sulfamethoxazole) tablets per day. Serum insulin levels were raised or inappropriately normal in 88% of cases in which they were measured, suggesting a sulfonylurea-like effect of co-trimoxazole as the mechanism of hypoglycaemia. All cases required intravenous glucose administration, and 43% experienced protracted (>12 hours) hypoglycaemia. Dosage adjustments should be made when prescribing co-trimoxazole to patients with renal dysfunction.

Hyperinsulinemic hypoglycemia associated with trimethoprim-sulfamethoxazole (TMP-SMX) has generally been reported in adults who had renal impairment or in patients with AIDS using high dose TMP-SMX. We present a 5 month-old infant with immunodeficiency due to major histocompatibility complex class II expression defect, developing hypoglycemic convulsion on the third day of high dose TMP-SMX administration. High insulin and C-peptide levels were documented at the time of hypoglycemia. To overcome hypoglycemia while TMP-SMX tapered off, diazoxide was administered which resolved hypoglycemia in 2 months.

The aim of this study was to evaluate epidemiological, clinical and laboratory data of shigellosis in children from northern Greece, hospitalized in our department during the period 1971-96. In total, 422 cases of shigellosis, aged 1 month to 14 y (238M, 184F) were hospitalized during the study period. The annual distribution was approximately stable until 1990, the mean number of cases per year being about 20. During the last 4 y the incidence significantly decreased. Shigella was serotyped in 138/422 cases. Seventy six of the strains were S. flexneri (55%) and 56 S. sonnei (40%). In the majority of cases the clinical picture was mild. Severe dehydration was seen in only 6 patients. Ninety four patients (22%) had extra-intestinal manifestations. Most common of these were convulsions (16%) and, less frequently, disturbances of consciousness (n = 26), rash (n = 9), shock and disseminated intravascular coagulopathy (n = 2), nerve paralysis (n = 2), severe anaemia (n = 2) and haemolytic-uraemic syndrome (n = 1). Nine patients had acute encephalopathy of 12 h to 12 d duration. It is important to note that all these cases recovered completely with no residual neurological deficit, except for 1 girl who developed temporal epilepsy 8 y later. Spinal fluid was normal in all 42 examined patients. Antibiotics were given to 212 of 422 patients, mainly during the first half of the study period. Shigella resistance to antibiotic was significant for cotrimoxazole (24%) and ampicillin (16%). All patients were cured. Shigellosis is a mild disease in our area, with a decreasing prevalence.

Whipple's disease is a rare, generalized inflammatory disorder due to the recently described bacterium Tropheryma whippelii. We report an unusual, successfully treated case of a 32-year-old woman, who presented with a 25 month history of large abdominal lymphomas, polyserositis and cachexia. The diagnosis of Whipple's disease was confirmed by duodenoscopy, lymph node and duodenal histology and polymerase chain reaction analysis of biopsy material and cerebrospinal fluid. A prolonged convulsive seizure with a subsequent 5 day period of coma were interpreted as signs of cerebral involvement. Under antibiotic treatment with trimethoprim-sulfamethoxazole (co-trimoxazole) the patient recovered completely, CT scans showed a complete regression of abdominal lymphomas. The therapy was continued over 18 months without the occurrence of a relapse.

A 55-year-old man became acutely psychotic and had a pseudoseizure after receiving six doses of intravenously administered trimethoprim-sulfamethoxazole. These symptoms resolved within 24 hours after discontinuation of the medication; this finding suggests a causal effect of the drug administration.
